COOKING-STOVE.

Application of Letters patent N 0. 7,144, dated March 5, 1850.

To all whom it may concern:

Be it known that I, CHARLES MURRY NEL- SON, of Cincinnati, Hamiltoncounty, and State of Ohio, have invented a new and useful Improvement inCoal Cooking- Stoves; and I do hereby declare that the following is afull and exact description, reference being had to the annexed drawingsof the same, making part of this specification.

Figure 1, is a perspective view of the stove. Fig. 2, is a perspectiveview of the stationary back plate of the fire chamber made with oblongopenings or passages for the draft, and the sliding register plate alsocast with openings or passages for the draftsaid openings being closed.Fig. 3, is a perspective view of the same partsthe openings being open.Fig. 4: is a perspective view of a portion of the interior of the stoveshowing the graduating valve A, hinged valve B,-side flue H and oven 0.Fig. 5, is a perspective view of the grate detached from the stove. Fig.6, is a perspective view of the ventilating bottom for keeping the potsfree from soot. Fig. 7, is a view of the right angled scraper forscraping the back and bottom fiue. Fig. 8, is a longitudinal section onthe dotted line 00 of Fig. 1, the valve A and register F, being inpositions to divide the draftcausing one half to pass over the oven andthe other half under it. Fig. 9, the register plate detached from thestove. In Fig. 1, the turning plate D, is in a position to act as ahood: in Fig. 8, it is in a position for replenishing the grate withcoal. The arrows show the direction of the draft when the register andvalves are in the position represented in Fig. 8.

Similar letters in the several figures refer to corresponding parts.

The nature of my invention consists in combining with the slidingregister at the back of the fire chamber a pivoted valve or damper Aarranged above the said register, which will admit all the heat, orpart, (at pleasure) to pass over the oven, or under it according to theposition of said register and valve.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I construct my stove, generally, in any of the known forms, as far asexternal and internal arrangements will admit, but in order to givegreater comfort with greater economy, I have found that the employmentof a pivoted damper or valve A in combination with the sliding registerF in the manner described prevents in a great measure the burning out ofthe back of the fire chamber by shutting the register to close theopenings in the back when the fire is being kindled causing the smoke topass off over the oven and directly up the pipe. I arrange the graduatedvalve, or damper A, which shuts off the passage over the oven topdirectly over the register and make its axle with a handle and hook orpoint that is to be inserted into one of the holes of a segmental rowmade in the side plate of the stove in which the handle is placed. Whenthe fire is in full blast and bright: this valve is placed in a positionto regulate the draft as required. Behind the register I haveconstructed a valve B, which, when opened, as seen in Fig. 8, admits theheat to a boiler placed in the space H, Figs. 1 and 4, which boiler willbe so arranged that hot water may be drawn from it at any time by a stopcock. A serious defect exists in common stoves which causes them to burnthe cakes &c., placed upon the griddles before they are thoroughlybaked, and to remedy this evil I have constructed double plates J, C,the upper plates or griddles J, Fig. 8, being made in the usual way, andthe under plates C next the fire, being constructed as slide damperswhich are shown one open and one closed at C, C, on Fig. 1. The movableor middle plate I is constructed in the form of a movable pan the bottomof which having holes to let the flame pass upward when the slidedampers C, C, are drawn out and which can be removed altogether when itis necessary to insert a large boiler.

In front of the stove over the doors, I have arranged a plate D to bethrown over upon top of the stove into a horizontal position as shown inFig. 8, when the fire re quires to be fed with fuel which prevents thesmoke and dust from being ejected into the apartment, during theoperation of replenishing the grate and the fire is not checked. Inaddition to the above I have constructed a movable bottom to the grateas shown at K in Fig. 5, which can be easily taken out when burned thinand replaced by a new one at a cost of a few cents.

The sliding pot bottom M, Fig. 6, is for the purpose of preventing anaccumulation of soot on the bottom of the pots when the fire iskindling.

The right angled or L shaped scraper is placed in the bottom and backfiues and. is designed for cleaning these fiues. The handle is seen at Ein Fig. 4. The slide that closes the opening in the bottom plate throughwhich the soot is discharged is, seen at L Fig. 4.

The horizontal valve V Fig. 1, for closing the back flue, When requiredis arranged upon the top plate of the oven near the smoke pipe in theusual manner and is provided With a handle by which it is movedhorizontally.

When the valve A is turned to the position represented by dotted linesand the valve V drawn across the back flue and the register F, and valveB, are open the heat Will pass through the mouth 72 into the side flue Hand out at the outlet 2' into the smoke pipe. When the register F isclosed and the valve A is open the draft Will be through the top flue.When the valve A is closed the register and valve V, are open the draftWill be through the bottom and back flue. l/Vhen the register and valveA are both partly open (as seen in Fig. 8) the draft will be both overand under the oven. By changing the angle of inclination of the valve AWith a vertical line the draft through the top flue may be increased ordiminished and regulated to the utmost exactness. The same result may beaccomplished through the bottom flue by moving the register to the rightor to the left by degrees.

Having thus fully described my improved coal cooking stove, What I claimas my invention and desire to secure by Letters Patent is Thearrangement of the valve or damper A, above the back plate of the firechamber, in combination With the register F, for regulating the draft,as herein fully set forth.

In testimony whereof I have hereunto signed lny name before tWosubscribing Witnesses.
